Description
Technical field
The present invention relates to technical field of lubricating grease, are applied to wind power plant yaw system more specifically to one kind
The lubricating grease and preparation method thereof of system gear.
Background technique
Wind power yawing system gear rouge is mainly used for the lubrication of great wind-power units yaw system gear, wind power yawing
The performance requirement of system gear rouge is determined by the specific operating condition and lubrication property of wind power plant yaw system gear.
The working principle of wind-driven generator is that the kinetic energy flowed by air acts on impeller, converts kinetic energy into mechanical energy, thus
Impeller rotation is pushed, the shaft of impeller is connected with the shaft of generator by gearbox, to drive electrical power generators.Wind-force hair
The main portions of motor include blade bearing, base bearing, gear-box, generator bearing, yaw system bearing and gear etc..Its
The effect of middle yaw system is can to make swept area of rotor always perpendicular to prevailing wind direction, although speed is not high, deflection bearing
The load that can be born with gear is larger, and therefore, it is usually necessary to use lubricating grease to be lubricated for yaw system gear.
Since wind power yawing system gear is chronically under larger load working condition, gear is easily caused to wipe if faulty lubrication
Wound, fretting wear are even glued；Moreover, deflection gears are generally open architecture, there is no generator bearing running speed fast, from
It is relatively smaller that body generates heat, thus climate environment is affected, it is contemplated that the valuableness of wind power equipment, many equipment are in remote
Area, working environment compare evil and omit, and scene is inconvenient to carry out detachable maintaining to capital equipment.By taking northwest China as an example, environment temperature
Reachable -20~-40 DEG C of low temperature, high temperature is up to 40~50 DEG C, and body surface temperature is up to 70~80 DEG C under solar exposure, it is contemplated that
Heat condition in Bearing gear operation process, wind power yawing system gear rouge operating temperature should be between -40~150 DEG C.Cause
This, just to wind power yawing system gear rouge, more stringent requirements are proposed for this, standard GB/T/T 33540.2-2017 wind-power electricity generation
Unit lubricant agent special has been unable to meet requirement.There are some wind power yawing system gear fat prods currently on the market, but right
Its base oil, additive concrete composition there has been no disclosed document reports, and wind power yawing system gear disclosed at present
Fat prod is not able to satisfy service performance requirement of the wind power yawing system gear under harsh environments still, and especially thermal oxide is steady
Qualitative, resistance to rust and corrosion and extreme pressure anti-wear.
Through retrieving, the lubricating oil about gear has related patents and discloses, for example, China Patent No.
201710502498.5, authorized announcement date is on 06 27th, 2017, invention and created name are as follows: it is a kind of it is high it is viscous refer to, wide temperature range
Industrial gear oil composition and its application.The Industrial gear oil composition of this application includes base oil and gear oil compounding agent；
The base oil includes hyperviscosity PAO base oil, the viscous finger hydrogenated base oil of height, APIV class base oil, and surplus is multiple for gear oil
Mixture.For another example, the application case that Chinese Patent Application No. is 201210130000.4 discloses a kind of manual transmission lubricating oil group
Object is closed, including at least one is compared with high viscosity index mineral oil or synthetic oil；With at least one viscosity index improver；It is at least one
Pour-point depressant；At least one phosphorous antiwear additive；The extreme pressure agent of at least one sulfur-bearing；At least one friction improver；It is at least one
Detergent-dispersant additive；At least one antioxidant；At least one antirust agent；At least one metal deactivator；At least one anti-foaming agent.
Above-mentioned two application case can improve the viscosity index (VI) of lubricant oil composite to a certain extent, but it is efficiently anti-
